As Ukraine is enduring one of the harshest winters of the war, Russian strikes continue to target the country’s energy infrastructure. In Kyiv alone, around four thousand buildings remain without heating and nearly 60% of the city has lost electricity following recent attacks. Across the country, communities face similar disruptions amid freezing temperatures. Volodymyr Zelensky has declared a state of emergency in the energy sector, with schools closed, public lighting reduced, and hundreds of thousands leaving the capital. He has also criticised the mayor of Kyiv, former boxer Vitali Klitschko, for not doing enough to restore power quickly. Hospitals have reported more than a thousand cases of frostbite and hypothermia in recent weeks. Emergency warming tents now dot the city, offering shelter and food. Germany has described Russian winter attacks on energy as war crimes, and the International Criminal Court has issued arrest warrants for two top military officials said to be responsible for them.
